Casio appears to be preparing two new G-Shock watches created in partnership with the Charles Darwin Foundation, continuing a collaboration that blends rugged watch design with wildlife-inspired themes from the Galapagos Islands.
The Japanese watchmaker has worked with the Charles Darwin Foundation several times before, including previous G-Shock releases such as the GAB2100DF-1A and GAB2100DF-4A. These special-edition models typically highlight animals connected to the Galapagos, where the foundation carries out important scientific and conservation work.
Now, fresh retail listings from Thai watch seller Hatyai Nalika suggest that two more models are on the way. The listed watches are the Casio G-Shock GA-B2100CDF-2A and the Casio G-Shock GW-B5600CDF-4. While Casio has not yet made a full official announcement, the listings and leaked images point to another nature-themed release with distinctive colorways and animal details.
The GA-B2100CDF-2A appears to feature a blue and beige design, leading to speculation that it may be inspired by the blue-footed booby, one of the Galapagos Islands’ most recognizable birds. Shared images suggest that the watch includes a small bird graphic, similar to the miniature animal detail used on earlier Charles Darwin Foundation G-Shock models.
The second model, the GW-B5600CDF-4, seems to take inspiration from the flamingo. This digital G-Shock is shown with a bright coral-toned resin bezel and strap, a red accent on the strap loop, and a camouflage-style frame surrounding the display. The bold color combination gives the watch a lively tropical look while staying true to the tough, square-shaped G-Shock identity.
These upcoming Casio G-Shock x Charles Darwin Foundation watches are expected to appeal to collectors, outdoor enthusiasts, and fans of limited-edition G-Shock designs. The combination of Galapagos wildlife themes, recognizable G-Shock durability, and unique color schemes could make both models highly attractive once they become officially available.
Casio is expected to announce the new collaboration models soon, with wider availability likely to follow after the official reveal. If the release pattern matches earlier Charles Darwin Foundation editions, these watches may launch in select markets first before reaching more regions globally.
